Extract

There are three particular pupillary movements in the course of the electrically-produced epileptic fit: dilatation during the convulsion, constriction in the post-convulsive stage, and spasmodic dilatation towards the final stages of the post-convulsive stage. The pupillary dilatation in the convulsive phase is identical with that found in the spontaneous epileptic fit, where it is generally considered as an expression of sympathetic activity, either the consequence of a general (Bumke, 1914) or of a focal cortical excitation (Foerster, 1936; Penfield and Erickson, 1941), or, an opinion held more recently, due to a hypothalamic mechanism (Delay, 1946).
